How can I create a plugin for Microsoft Pub Center?

I’m trying to add some ads to my Windows 8.1 videogame but I’m stuck. I’ve tried to use the Microsoft Ads Plugin from Prime31 but I get an error. Has anyone use Microsoft Pub Center with Unity before?

Hi, I was looking in web, and I found this plugin to integrate Microsoft PubCenter ads in Unity. I haven’t tested this plugin yet, but I think this will be working fine, so this is the link. Good luck! Plugin
